CANADA, -ASSIGNOR TO SUN INVESTMENT con-renames, orrrorvrnian amnion CARD Application filed November This invention relates .to new and. useful improvements in visible cardindexes and the object of the invention is to provide a multiple section card holder which will automatically uncover one edge of the cards when the holder is in the open position to allow the cards to be withdrawn without bending same; but which will retain the cards in their respective sections when the holder is in the 19 closed or closing position.

According to my invention, I provide a holder made in sections hingedly attached to one another. Each section is provided with a flange adapted to overlie the edges of the 153 cards remote from the hinge. Overlying or extending upwardly from the hinge 1s a member, which covers or contacts with the edges of the cards adjacent the hinge to hold the cards in their respective sectionswhen' the holder is in the closed or closing position; but which trees or clears the said edges when the holder isin the open position to facilitate the manipulation of the cards in the sections.

In the drawings which illustrate my invention: I

Figure 1' is a plan view of my preferred form of holder in its open position.

Figure 2 is an enlarged sectional elevation taken on the line 2-2, Figure 1.

Figure 3 is a view somewhat similar to Figure 2 but with the holder in the closing position. V

Figure 4 is an enlarged transverse section of the holder shown in Figure 1 but with the sections in the closed position.

Figure 5 is an enlarged view of a holder similar to Figure 3 but with a modified type of hinge.

Figure 6 is an enlarged view showing a Figure 7 is a fragmentary perspective View of the card indexing member.

Referring more particularly to the drawings, and especially to Figures 1 to 4 inclusive, the holder consists of two sections 11 and 12, the adjacent edges 13 0f which are turned upwardly and hingedly attached to each other by the flexible strip 14. The remote side edges 15 and 16 are turned up-.

wardly and inwardly to provide guide chanmodified card-retaining member and hinge.

nels for the sides. of the cards 17 remote from the hinge. The ends 18 and 19 of the sections are preferably turned upwardly and inwardly to form flanges, The inwardly turned sides and ends contact with'one an other when the holder is in the closed position. When the holder is in the open position, as shown in Figures 1 and 2 the sides of the cards adjacent the hinge are left free so that the cards may be Withdrawn from the holder without bending them.

My improvement lies in providing means at the hinged portion of the holder to automatically engage with the edges of the ad jacent sides of the cards to hold them in their respective sections when closing the holder and which will clear said edges when in the open position.

In Figures 2 to'5 inclusive, this is accom-- plished by providing a flexible member 20 which overlies the hinge and is secured to the adjacent sides of the sections. As will be seen, thismember extends above the pivot point of the hinge. On closing the holder, this member- 20 tends to bulge out or form a ridge on each side of the hinge to overlie the edges of the cards adjacent thereto to hold them in the sections but when the holder .is open, said member lies close to the hinged side of each section and clear of the cards so that they may be easily withdrawn. In Figure 5, the sections 11a and 12a are secured together by a hinge pin 21 and'theflexible member 20 is substantially the same as that disclosed in Figures 1 to 4..

. Referring to the form of invention disclosed in Figures 6 and 7 it will be noted that the sections 11?) and 126 are coupled to.-

gether' by hinge pin 21?) passing through suit able-hinge eyes 210 carriedby the adjacent a edges of said sections, as shown to advantage in Figure 7. A plurality of members20a are secured to the pin 21?) at intervals along the length of said pin. These members 2062 V are adapted to lie clear ofand substantially at right-angles to or adjacent and parallel .to-the face of the cards of one or the other seetions'when the sections are in open position. Each member 20a preferably consists of a piece of plate doublhd around the hinge pin and in frictional cont-act therewith. When the sections are closed, the members 20a will eventually lie substantially parallel to the faces of the cards and serve to retain the adjacent edges of the cards in place.

In the drawings, the holder is shown with two sections, but it will be readily understood th more tl an two sections may be hingedly attached to one another and provided with members 20 or 20a at the hinges without departing from the spirit of the invention.

Having thus described my invention, what I claim is 1. it visible card index comprising a pair of box sections having their inner sides hinged together, flanges projecting inward- 1y from t Y 01" said sections to form ch: 7 eiving the outer side edges of the cards placed in said sections, and a card retaining member carried by the hingedly CODHGLLOd lee of said sections said member overlying hinge and adapted to clear the inner side edges 015 the cards when the sections are in the open position and to bulge outwardly to form flanges overlying the said inner side edges of the cards at each side of the hinge when the holder is in the closed position.

2. A visible card index comprising a pair of b 2: sections having their inner sides hinged together, flanges projecting inwardly from the outer sides of said sections to form channels for receiving the outer side edges of cards placed in said sections, and flexible member presenting side portions secured to and lying close to the inner side walls of said sections the intermediate portion of said flexible member being arranged to bridge the hinge connection between the inner sides 01"- said sections and being projected beyond said hinge connection and clear of the inner side edges of said cards when the sections are in the open position, the said intermediate portion of the flexible member being also adapted to bulge outwardly to form card-retaining ridges on each side of the hinge upon closing of the sections.

A holder "for index cards comprising a plurality of sections having their inner sides hingedly connected togethe1',tla1iges extending in\ 'ardly from the onter sides of said sections and adapted to overlie the outer side edges of cards placed in said sections and card-retaining means carried by and projecting inwardly beyond the hingedly'connected sides of said sections, said means functioning to engage over the inner edges of the cards when the holder is closed and to automatically clear the said inner edges of the cards when the holder is opened.

4. A holder for index cards comprising a plurality of box sections having their inner sides hingedly connected together, flanges projecting inwardly from the outer sides of said sections to term channels receiving the outer edges of cards placed in said sections and a card-retaining member carried by the hingedly connected sides of said sections and projecting inwardly beyond the hinge connection, said member being disposed at right angles to or adjacent and parallel to and clear of the inner side faces of the cards of one or the other sections when the sections are in open position but being adapted to be brought into overlying engagement with the said faces of the cards when the box sections are moved to closed position.

5. An index card holder comprising card receiving sections having their inner sides ringed together and their outer sides equipped with card retaining flanges and means mounted at the hingedly connected sides of the sections to form a retaining flange tor the inner edge portions of the cards durthe closing and closed positions of the secsaid means automatically assuming a po tion leaving the inner edge portions of the ards in at least one of the sections expo .7 and accessible for removal when the sections are in open position.

In witness where t, I have hereunto set my han d.
